BOW-FACING OAR- Specification of Letters Patent.

Patented July 10, 1906.

Application filed December 11, 1905- Serial No. 291.183.

To all Hill/TH it may concern.-

Be it known that W6,.JACOB WILLIAM VVAGNER, residing at Garrett, and HENRY SI-IENK, residing at Cedar, in the county of Dekalb, in the State of Indiana, citizens of the United States, have invented certain new and useful Improvements in Bow-Facing part of this specification.

' shown in vertical section.

Our invention relates to bow-facing oars.

The object of our present invention is to provide a cheap, simple, efiicient, and convenient bow facingoar mounted on a pivotal supporting-plate provided with two fulcrums to materially increase the leverage and enable the operator to face the bow of the boat. a novel means of mounting the su porting-plate, and. a novel self-locking pin for securing the plate in position.

Our invention consists of an upright supporting-bracket rigidly fixed to either the inner or outer face of the gunwale of the boat on which it is employed, a swinging late horizontally mounted on the bracket y a detachable connection of novel construction, and a two-part oar mounted on the said plate and rovided with two separate and independent ulerums.

The principal novel features of our invention reside in the two-fulcrum construction and arrangement of the oar and the means for detachably mounting the same.

Similar reference-numerals indicate like parts throughout the several views, in which Figure 1 is a perspective view of our invention in position on the side or gunwale of the boat, broken away and showing the relation of the operative parts. Fig. 2 is a detail of the pivoted sleeve by which the forward sec.- tion of the car is guided, the sleeve being Fig. 3 isa side view of the oar-supporting bracket in posiimprovements in tion on the side of the boat.

The upright supporting-bracket 1, of any proper size and contour, is rigidly secured to either the inner or outer face of the side or guuwale of the boat, as shown in Fig. 3, in

' topped sockets 4.

' sition any proper manner, as by screws 2, and is provided at its ends with the upright lugs .3, having their upper end provided with open.- This bracket is also provided at its central portion with a pair of upright laterally-apertured lugs 5, adapted to receive the pin 6,. having a head on one end and its other end provided with centrally-pivoted section 7, adapted to retain a vertical position in use by gravity, as shown in Fig. 3, thereby securing the pin in position.

On the bracket 1 is pivotally mounted the oar-supporting plate 9, Fig. 1, whose inner end is provided with theextended bifurcated lugs 10, provided with a fixed pin 11, adapted to form a bearing in the respective sockets 4 of the bracket-lugs 3. This plate is also provided at its inner end, midway of the lugs 10, with a laterally-apertured lug 12, adapted to be loosely mounted between the said lugs 5 and to be pivotally secured thereto by means of the said removable pin 6. In a suitable aperture in the lug 12 is fixed a verticallv-- arranged pin or bolt 13, on which is pivotally mounted the handle-section 14 of the twoart oar. This section 14'has its outer end ifurcated and adapted to loosely receive the reduced inner end of the paddle or other sec-. tion 15 of the oar. This oar-section 15 is loosely or slidably mountedat .or near its inner end in an upright guide stirrup or sleeve 16, which is pivotally mounted 1n the extended outer end of the plate 9 in any suitable manner, preferably y means of a pendent screw 17, on which are preferably. ar-

ranged a pair of washers 18, one on each side of-the late 9, the whole being secured in poy means of a nut 19 on thescrewthreaded outer end of the screw 17 Fig. 2. This guide 16 forms a pivotal fulcrum for the blade-section.

The operation of our invention thus described is obvious and, briefly stated, is as follows: Referring to Fig. 1, either end of the gunwale 8 may be considered as pointing to-- ward the bow of the boat, though for convenience of description it is assumed that the gunwale 8, which is shown, is upon the left side of the boat, and theoperator faces the bow or in the direction of the arrow, thereby operating the oar shown with his left hand and its exact'duplicate (notshown) with his right hand. When it is desired to propel the boat forward, the operator seizes the handlecan sections of the oars and first pushes them forward on their fulcrum 13 in the usual manner, thereby correspondingly swinging theinner end of the blade-section 15 rearwardly on its ivotal fulcrum 16, whereby the blade 20 WiIl be swung correspondingly forward into position for the stroke or efiective movement thereof, after which the operator pulls on the oars simultaneously, thereby bringing the oar- 'bladesrearwardlyintheir effective movement.

a In the forward or return movement of the o'ars the operator bears down on the handle-secs tions of the oars sufficiently to properly tilt the outer end of the plate 9 upwardly, there:

enabling the blade-sections of the oars to b cheer the surface of the water during this movement. It is obvious that by this construction theoperator, who faces the bow of the boat, can propel the boat forward instead of backward-and that the relative position of the ivoted fulcrums for the blade-section be variously placed to suit the operator. To remove the oars, with their 'supportingplate, it is only necessary to "swing the piv' oted section 7 of thepin 6 into its ongitudinal position and thenremove the pin, after which'the plate 9,-' With its surmounted oar,

What we desire to secure by Letters Patent.is

L In a bow-facing oar the combinationfof an upright bracket provided at its ends with open socket-bearings and at its central portion with laterally-apertured lugs; a horizontal plate pivotally mounted in the bearingsand lugs of said bracket, and provided upon its outer free end with 'a pivotedstirrup or guideyand' a two-part oar whosehandle-section is fulcrumed near the inner edge of the said plate, and --whose blade-section is .slid-' ably mounted in the said guide and is pivot ally connected at its inner end to the said handle-section, all substantially as described.

2. The combination in a bow-facing-oar of an upright bracket having open socket-bearingsat 1ts ends, and provided with laterallyapertured lugs at its central portion; a horizontal plate resting in the socket-bearings, and having. an apertured lug which extends between the before-mentioned lugs, and a re movable bolt' extending through all of said lugs; and a two-part oar connected withthe horizontal late and supported thereby, whose hand e -section is ful'crum'ed near the inner edge 'of the said plate, and whose blade section is slidably mounted in the said-guide, andis pivotall connected at its inner end to the said hand e -section, allsubstantiallyas described. 1
